Diffusion and absorption simulation

Please login with a confirmed email address before reporting spam

Hello

I want to calculate the rate of absorption and diffusion of water from humid air into a solid material. However, I can only find information in COMSOL about diffusion spreading inside one material.

Can I model absorption and diffusion from a gas into a solid?

Thanks for any help

Hi

Please check the tutorial of the reverse process, evaporation from porous material. It gives the appropriate boundary conditions etc.

Thank you Lasse. Do you have any recommendations for which module/modules to run? I have been looking at Transport of Diluted Species and Species Transport in Porous Media.
